System and method for routing telephone calls
First Claim
1. For use in an Advanced Intelligent Network (AIN) equipped with Terminating Attempt Trigger (TAT) and terminating Next Event List (NEL) functionality and having at least one Central Office Switch (COS) and a Service Control Point (SCP) in electrical communication with a plurality of Subscriber switches via a signaling network, a method of routing a telephone call from a Caller to a Subscriber telephone line, comprising:
- providing an Intelligent Peripheral (IP) in electrical communication with the at least one COS and the SCP, the IP equipped with queuing functionality for each of the Subscribers;
monitoring the signaling to detect a TAT trigger;
launching a query at the SCP for receipt by the IP requesting the queue status of the Subscriber line in response to the detected TAT trigger;
forwarding the call to the IP to be added to the queue in response to a determination that the queue is active;
delivering the call to the Subscriber and setting a NEL to determine the status of a Subscriber'"'"'s line in response to a determination that the queue is empty;
connecting the call to the Subscriber'"'"'s line in response to a determination that the line is idle;
forwarding the call to the IP to be placed in queue in response to a determination that the Subscriber'"'"'s line is busy;
monitoring the Subscriber'"'"'s line to notify the SCP when the line is idle;
placing a call at the IP to the Subscriber in response to a determination that the Subscriber'"'"'s line is idle;
forwarding answer supervision to the IP in response to the call being answered by the Subscriber; and
,transferring and connecting the Subscriber and the Caller at the COS.

Abstract
A method of routing a telephone call from a Caller to a Subscriber telephone line in an Advanced Intelligent Network (AIN) equipped with Terminating Attempt Trigger (TAT) and Terminating Next Event List (NEL) functionality and having at least one Central Office Switch (COS) and a Service Control Point (SCP) in electrical communication with a plurality of Subscriber switches via a signalling method and system. The system includes an intelligent peripheral in electrical communication with the COS and the SCP and which is equipped with queuing functionality for each of the Subscribers and operative to place a call to the COS for receipt by a Subscriber having a call placed in queue in response to a determination that the Subscriber'"'"'s line is idle.

7. For use in an Advanced Intelligent Network (AIN) equipped with Terminating Attempt Trigger (TAT) and terminating Next Event List (NEL) functionality and having at least one Central Office Switch (COS) and a Service Control Point (SCP) in electrical communication with a plurality of Subscriber switches via a signaling network, a method of routing a telephone call from a Caller to a Subscriber telephone line, comprising:
-
providing an Intelligent Peripheral (IP) in electrical communication with the COS and the SCP, the IP equipped with queuing functionality for each of the Subscribers; monitoring the signalling to detect a TAT trigger; generating a first electrical signal for receipt by the SCP in response to the detected TAT trigger; generating a second electrical signal at the SCP for receipt by the IP requesting the queue status of the Subscriber line; generating a third electrical signal at the SCP for receipt by the Subscriber switch instructing the Subscriber switch to forward the call to the IP to be added to the queue in response to a determination that the queue was active; generating a fourth electrical signal at the SCP for receipt by the Subscriber switch instructing the Subscriber switch to deliver the call to the Subscriber and set a NEL to determine the status of the Subscriber'"'"'s line in response to a determination that the queue is empty; connecting the call to the Subscriber'"'"'s line in response to a determination that the line is idle; generating a fifth electrical signal at the Subscriber'"'"'s switch for receipt by the SCP in response to a determination that the Subscriber'"'"'s line is busy; generating a sixth electrical signal at the SCP for receipt by the Subscriber'"'"'s switch instructing the Subscriber'"'"'s switch to forward the call to the IP to be placed in queue; generating a seventh electrical signal at the SCP for receipt by the Subscriber'"'"'s switch instructing the Subscriber'"'"'s switch to set a monitor on the Subscriber'"'"'s line and to notify the SCP when the line is idle; generating an eighth electrical signal at the Subscriber switch for receipt by the SCP in response to a determination that the Subscriber'"'"'s line is idle; generating a ninth electrical signal at the SCP for receipt by the IP instructing the IP to call the Subscriber via the COS; generating a tenth electrical signal at the COS for receipt by the IP to forward answer supervision to the IP in response to the call being answered by the Subscriber; and
,generating an eleventh electrical signal at the IP for receipt by the COS to transfer and connect the Subscriber and the Caller at the COS.
